Abstract

The main features of power generating industry contempo-rary stage are transition to the new technological platform based on smart grid concept. This concept is fully applicable in Railroad Power Systems. Implementation of smart Railroad Power Systems would allow solution of the following practical issues: ensuring high level of power supply reliability; enhanc-ing electromagnetic safety (ES); minimization of power losses and costs for Railroad Power Systems operation; enhancing power quality in Railroad Power Systems and in connected power systems. Implementation of smart Railroad Power Sys-tems requires development of computer-based technologies for modes and electromagnetic fields simulation that determine electromagnetic safety conditions. The methods of defining modes in phase coordinates developed in Irkutsk State Transport University allow carrying out simultaneous calcula-tions of electromagnetic fields (EMF) intensities of multi wire lines when determining the mode of an external power system (EPS) and traction power supply system (TPSS). In this case, the line under consideration is viewed inseparably with com-plex EPS. Simultaneous calculation of the mode and created EMF allows implementation of the system approach [5, 6] to analysis of electromagnetic environment. Its distinct feature is a possibility of EMF simulation with due regard for all prop-erties and characteristics of the complex TPSS and EPS. Elec-tromagnetic environment management can be reduced to the issue of magnetic field reduction in given points of tractive network space. Methods for this issue solution are divided into technical and mode ones. The following actions are referred to as technical ones: the use of autotransformer TPSS 2х25 kV; the use of suction transformers with return conductor; instal-lation of adjuvant wire and shielding wire; the use of passive screens installed on passenger platforms. Optimization of train operation schedules and train operation modes are re-ferred to the mode actions in accordance with ES enhance-ment criterion, as well as the use of automatic train operation with algorithms aimed at peak loads reduction. Magnetic field intensity can be reduced by the use of trains’ optimal opera-tion schedule, and by the use of “soft” modes for trains’ oper-ation. The last action is capable reducing magnetic field inten-sity peak values by approximately 25 %.
